API Reference > geometry-core > CartesianGeometry > ClipPlane > appendIntersectionRadians appendIntersectionRadians Method Compute intersections of an (UNBOUNDED) arc with the plane. Append them (as radians) to a growing array. appendIntersectionRadians(arc: Arc3d, intersectionRadians: GrowableFloat64Array): void Parameter Type Description arc Arc3d arc to test. The angle limits of the arc are NOT considered. intersectionRadians GrowableFloat64Array array to receive results Returns - void Defined in clipping/ClipPlane.ts Line 367 Last Updated: 12 June, 2024
